Another folded style.
There is a number of glyphs I would've rather seen different, like for example G, V, Y, 4, maybe 7. And the punctuation is very poorly done too. But I got kind of stuck and didn't know where to take it any further,
so...
Enjoy nonetheless
My own Escher-style font, based on the title of dutchprofiles.com :
Allows multicoloring, blanks and 3D effects.
